1 BRAKE-SHOE.

SPECIFICATION forming part of Letters Patent No. 739,605, datedSeptember 22, 1903.

. Application filed OotoherQ, 1902. :Serial No. 12?,3 73. (No model.)

For the purpose of securing the shoe proper to the head severaldifierent forms of fastening devices have been adopted, that mostgenerally used consisting of a hook or'l-ug cast integral with the shoeand at one end thereof, under which fits the corresponding end of thehead, the opposite end of the head being secured to the shoe by means ofa bolt or post passing through openings formed in said shoe and head,said bolt or post being enlarged at one end to prevent its passageentirely through the opening in the shoe properand its opposite endbeing provided with a slot or opening for the passage of a key. Thesefastening devices, however,'have met with several objections'namely,that the iron lug or hook is frequently broken in handling and duringtransportation, thus rendering the shoe absolutely worthless. Further,in order to allow the insertion ofone,

end of the head under the cast-iron hook or lug in assembling the partsthe bolt or post must be removed, thereby necessitating the formation ofthis part as a distinct and separate piece from the shoe andhead. Topartially overcome these objections, it has been attempted to form thehook or lug of a separate piece, usually of steel or other comparativelyhard and tough metahand anchor or secure the same in the metal of theshoe during the casting operation. Such construction, however, has beenfound impractical, owing to the fact that the metal around the base ofthe hook or lug becomes too rapidly chilled or cooled, and as there isbut a small quantity of metal between said base and the extreme end ofthe shoe the strength of the latter is thereby greatly impaired, and,further, the belt or post for securing the opposite end of the shoemust, as in the first instance, be made separate and removable from theother parts or portions of the head and shoe.

The object of my present invention is to overcome the objections raisedagainst the above and other forms of fastenings; and it consists incertain novel features of construction and combinations of parts, aswill be hereinafter fully described, and specifically pointed out in theclaims.

In the accompanyingdrawings, Figure 1 is a plan view of a brake-shoeconstructed in ac cordance with my invention. Fig. 2 is a side viewthereof with the head attached, the head being shown partly in section.Fig. 3 is a similar view showing the position of the head during theoperation of assembling the two parts. Fig. 4 is a detached view inperspective of the fastening-hook.

' Referring to the drawings, 4 represents the head, and 5 the shoe, theformer consisting of two side plates or flanges 6 and the base-.

plate '7. V

In one end of the shoe 5 is secured the hook 8, preferably formed from awrought or malleable iron bar or rod and bent into the form asillustrated in Fig. l-that is, with the two horizontal arms 9 and theloop 10 forming the hook proper, the loop being inclined, as illustratedin Fig. 3, in order to allow of the insertion of one end of the plate 7under the same, while at the same time the opposite end of the plate israised in order to clear the top'of the bolt or post 11, hereinafterreferred to, in assembling the parts. To moresecurely anchor the hook inthe cast metal of which the shoe 5 is formed, the ends of the arms 9 aresomewhat flattened, as shown at 12, the book being inserted in the moldduringthe operation of casting.

In the opposite end of the shoe is secured the post or bolt 11, itslower end-13 being the hook 8, being inserted in the mold during thecasting operation, and thereby securely held in themetal of thecast-iron shoe.

, In assembling the parts one end of the plate 7 of the head is insertedunder the inclined hook or loop 10, the opposite end of the plate 7being raised, as illustrated in Fig. 8. The post 11 is then passedthrough the opening 16, formed in the plate 7, as illustrated in Fig.2,whereupon the key 15 is passed through the opening 14 in the post 11,looking those respective ends of the head and shoe together. By a slightblow upon the hook or loop the latter is then bent downwardly until itbears upon the upper surface of the plate 7, as illustrated in Fig. 2,thus completing the locking together of the head and shoe.

In order to subsequently detach the head 4 from the shoe 5, it is simplynecessary to remove the key 15 from the post 11, whereupon that end ofthe head may be raised until it clears the top of said .post, thetilting of the head slightly bending the hook 10 and allowing of thewithdrawal of the plate 7 from engagement therewith.

From the foregoing it will be understood that the objection to the loosepostis entirely overcome, and, further, that by forming the hook from amalleable or wrought iron bar or rod it will have a far less chillingeffect upon the iron during the casting of the latter than when formedin the manner as first suggested, is far cheaper, and more safely andsecurely anchored in the shoe.

Having fully described my invention, what 1 claim as new, and desire tosecure by Letters Patent, is-

1. A brake'shoe having, as a means for attaching to a brake-head, amalleable wire skeleton hook.

2. A brake-shoe having as 'a means for attaching to a brake-head, amalleable wire hltlqok embedded by casting in the metal of the s 00.

'wardly upon the head when the parts are assembled, and provided at itsopp site end with a malleable embedded stationary post, substantially asdescribed.

5. A brake-shoe consisting of a body portion provided at one end with ahook, said hookbeing formed from a wrought-metal bar or rod, theopposite end of the body of the shoe being provided with a post,substantially as described.

6. A brake-shoe consisting of a body portion provided at one end with ahook, said hook being formed with two horizontal arms and a loop or hookproper, and means provided at the opposite end of said body portion forseeuringit to the head, substantially as described.

7. A brake-shoe consisting of a body portion provided at one end with ahook, said book being formed from a wrought-metal bar or rod and withtwo flattened horizontal arms and a loop or hook proper, said horizontalarms being anchored in the metal of which the body is formed, and meanslocated at the opposite end of the shoe for fastening the same to thehead, substantially as described.
